4 Claims.

This invention relates to safety razors of the magazine type which are organized to receive fresh sharp blades, one by one, from a magazine simultaneously with the discharge of a used blade. Heretofore, the discharged blade has been shot out of the razor much as an empty shell is ejected from a magazine rifle, and in fact certain safety razors of this type are known as repeater razors on account of the close analogy.

The snappy discharge of the used blade pleases 3 nate the hazard above discussed by providing means for temporarily holding th used blade in convenient position in the razor head after it has been duly removed from the blade seat. For example, the blade may be held projecting into space from the razor so that the user may conveniently and safely take hold of it for the purpose of disposing of it where it can do no damage.

Going more into detail, my invention consists in the combination of a safety razor having elongated blade-clamping members with a thin, elongated blade sharpened at one edge and yieldin ly held by said members with its sharp edge exposed for shaving, together with spring means for urging said members into blade-clamping position but permitting them to be forcibly separated for endwise movement of a blade between them, and co-operating means associated with the blade-clamping members and the blade it self for temporarily holding the blade in a position in which it projects from the safety razor after its cutting edge has been advanced longitudinally beyond the end of said clamping members in the discharge movement of the blade.

These and other features of the invention will be best understood and appreciated from the following description of several preferred embodiments thereof selected for the purpose of illustration and shown in the accompanying drawings, in which:

Fig. 1 is a view in perspective on an enlarged scale of a safety razor and magazine shown in operative relation;

Fig. 2 is a view of the razor in cross section; Fig. 3 is a fragmentary end view of the razor in perspective;

' the back plate I forwardly to form the blade seat 14 which is Fig. 4 is a modification of the razor shown in 'Figure 3; and

Figs. 5 and 6 are views in perspective showing 7 blades of two different contours.

My invention is herein shown as embodied in a safety razor for single dged blades having a handle I G from the upper end of which projects an upright back plate Ii.

This extends upwardly and is then bent forwardly and downwardly to form the upper stationary clamping plate I 2 of the razor. A front plat I3 overlies It extends upwardly and then located beneath and parallel to the upper clamping plate 12. The two plates are movably connected by a tongue l5 which is struck out of the material of the back plate, carried through a slot in the front plate and bent downwardly so as to overlie it. A curved spring I6 is riveted to th shank of the back plate and bears resiliently upon the reentrant angle formed between the back plate l3 and the overhanging blade seat 14. The blade seat 14 is extended forwardly and downwardly to form a guard H. A pair of rounded lugs It project upwardly from the re spective front corners of the blade seat. These lugs serve to gaug the blade in shaving position. It will be seen that after a blade has been advanced endwise into position upon the blade seat 14, the pressure of the spring ISagainst the front plate tends to force the blade seat and the two lugs 18 rearwardly, thereby moving the back of the blade against th angle of the back plate 1-H and engaging the corner edges of the blade against lugs l8.

, As temporary blade-holding means, I provide the razor shown in Figs. 1-3 with an auxiliary blade clamp 2i]. This may be formed as herein shown by extending a portion of the blade seat M outwardly toward the left as seen in Figs. 1 and 3, and bending such extended material into the form of a spring clamp, as best shown in Fig. 3. The opening in this clamp, of course,

is aligned with the opening between the clamprow, elongated single-edge blade of the proper dimensions to occupy the blade seat of the razor with its cutting edge exposed above the guard l7 and securely clamped in position by the action of the spring I E.

The blades 2! may be supplied to the razor from a magazine 22 of well-known construction and forming no part of the present invention. The magazine herein shown is provided internally with means for locating within it a stack of blades 2|. with a blade-exit slot 23 and with a projecting key or finger 2 3, shown only in Fig. 2, which is adapted to be inserted in the space between the back plate i i and the front plate l3, forcing them slightly apart against the pressure of the spring I6 and relieving the pressure of the blade edge upon the lugs it so that the used blade maybe advanced along the blade seat and a new blade moved into its place.

The magazine is also provided with a bladefeeding slide 25 which is arranged to reciprocate upon the magazine and to engage and eject in each forward movement the blade uppermost in the magazine. In Fig. l, the feed slide 25 is shown in the position it occupies at the end of its feeding stroke. In this stroke it has placed the blade 2| properly in its longitudinal position in the razor and the blade 2! has ejected the blade 2| from the blade seat and left it temporarily held by the spring clamp 29. When the user removes the magazine, the key 24 is withdrawn from its position in the razor and the spring Iii acts to clamp the blade 2| in shaving position.

, The user may now conveniently pick off the used blade 2|. and dispose of it.

In Fig. 4 is shown a modified razor structure comprising another embodiment of my invention and in which the means for temporarily holding the used blade is provided by forming an extension 26 on the left end of the plate l2 and a corresponding'projection 2? on the end of the bladeseat l4. These two extensions act as a clamp to engage the rear end of a blade which has been pushed beyond the end of the blade seat and to hold the blade temporarily in a projecting position.

In Figs. and 6 are shown blades modified in their end contour to facilitate the temporary holding action as above explained. The blade 28 is notched to provide a rearward extension 29, and the blade 30 is notched to provide a rearward extension 3!, that remains between the clamping elements of the razor when the succeeding new blade has been pushed fully upon the bladeseat. It will be noted that my invention contemplates extending either the clamping members themselves or the blades in order to provide the delayed engagement which is desired between the razor and the used blade.

Having thus disclosed my invention and de- At its left-hand end, it is provided.v

4 scribed in detail illustrative embodiments thereof, I claim as new and desire to secure by Letters Patent:

1. A safety razor having in its structure opposed blade-clamping members, resilient means urging them into blade-clamping position, and a spring clamping device located adjacent to said members for engaging and temporarily holding an otherwise loose blade advanced through and beyond the space between said clamping members.

2. A safety razor having in its structure opposed blade-clamping plates, one shaped to support and the other partially to cover a thin elongated blade, said plates being substantially coextensive in length and separable to permit a blade to be moved frictionally in an endwise path between them, and a blade holder located beyond the blade-clamping plates for temporarily holding an otherwise loose blade after it has been extracted from between the said clamping plates.

3. A safety razor having in its structure elongated blade-clamping members spring pressed into engagement with an interposed blade and arranged to be forcibly separated whereby a blade may be advanced lengthwise from between them, and a blade holder located adjacent to one end of said members in position to engage and temporarily hold an otherwise loose blade after it has been advanced out from between said members.

4. A safety razor having, in combination, elongated blade-clamping members, a thin elongated blade sharpened at one edge and yieldingly held by said members with its sharp edge exposed for shaving, spring means for urging said. members into blade-clamping position but permitting them to be forcibly separated to permit endwise movement of a blade betweenthem, and a spring operated cooperating device associated withrthe blade-clamping members and the blade for temporarily holding an otherwise loose blade after its cutting edge has been advanced beyond the end of said members.
